I'm making hack&slash game and I want my characters move like for example in Torchlight, Diablo, etc. Currently I generate set of nodes for all walkable areas of a floor. When I click somewhere player goes there through interpolated path of nodes. This doesn't look very natural. Player moves like a robot. Enemies also use this node system for movement and share the same issue but I have one more problem with them. When enemies detect player they go to him by a shortest path. Sometimes they use the same path and line up to the player instead of surrounding him. I don't know how to make enemies choose different paths and surround the player. Do you know how can I solve this problems? Maybe I should use different approach for character movement?
My current technique:
I want to know how to deal with these situations:
Situation 1, I have dynamic/static obstalces on my way
Situation 2, Enemies have the sam path to player ( get into queue to fight with us )
